2022 RAM Promaster

I bought a New Dodge Ram 3500 cargo van in 2022. The van currently has 48,000 miles and the steering started violently pulling, almost causing a wreck on a couple of occasions. I took into the dealership and they said the wiring harness for the steering rack is bad and not under warranty. This is a manufacturer defect, looking online there are hundreds of cases just like mine, with a couple of serious wrecks. The manufacture knows that water is getting in the steering harness wiring, causing it to short out and corrode. The dealership is telling me that not only is the part not under warranty, but they don't have it and have no idea when they will get this part. I had the exact same issues with another one of my vans last year. it took six months for the repair part to come in. Two vans, one with 20,000 miles and one with 48,000 miles, both the same issues and the same issue getting the correct replacement part.

The contact owns a 2022 Ram ProMaster 1500. The contact stated while reversing, the steering wheel failed to turn in the intended direction and jerked, the forward collision avoidance warning light illuminated, and the transmission failed to shift into reverse(R) or neutral(N). Several unknown warning lights later illuminated. The contact stated that the failure was a known issue. The contact stated that the vehicle was inoperable. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 11,500.

Intermittent 'Service Power Steering' and LaneSense warnings first appeared in May 2026. Repair shop found Diagnostic trouble code C1593-49 - Steering torque sensor circuit/internal electronic failure. The repair shop found water intrusion and corrosion at steering electrical connector(s). Cleaning did not resolve the fault. Diagnosis: Internal steering torque sensor failure. Sensor is integral to the electric steering rack; complete rack replacement required. Photos are available for inspection. Safety of the driver and all others on the road was at risk, as the 2022 Promaster 3500 is a heavy vehicle that could become unmanageable without power steering. Problem was confirmed by EAS Tire and Auto in Lafayette, Colorado. The component was returned to Mopar when the new component was ordered. This issue is an additional example/complaint to NHTSA Investigation PE26-002 for intermittent or complete loss of electric power steering, including reports involving water intrusion and corrosion affecting the power steering system. My vehicle exhibits substantially similar symptoms and diagnostic findings. I have a finalized repair invoice, diagnostic report showing DTC C1593-49, and photographs of corrosion/connectors.

The forward collision light has been on but has not been affecting driving. Since I saw that here I figured it was worth mentioning. I have mentioned this to the dealership that is handling the current recalls as well. The more pressing issue is the steering. It happened once before where I was backing up and the steering wheel became difficult to rotate and violently jerking back against the direction of rotation. After shutting down the van and restarting it the issue had seemingly gone away. I emailed RAM about this initial occurrence but have yet to hear back. Last night, July 26, 2026, the issue occurred again as I was attempting to back out of my driveway. As I tried to turn the steering wheel it seemed to "fight" me, becoming difficult to rotate and violently jerking the other way against the direction I was attempting to rotate it. I switched from reverse to drive and was able to re-park the van where it was parked prior. My safety was not compromised in any considerable manner as this occurred at low, "driveway" speed. It was just me in the vehicle with no one else around. The problem has not been reproduced by a dealer yet nor has it been inspected by a dealer or service center. The warning lamps for the ESC and EPS came on once the problem began occurring but seemed to turn off after restarting. The problem appears to be currently intermittent in nature but, based on other accounts, the fact that this is occurring is seemingly indicative of a more serious issue in how this vehicle was manufactured. My concern is this happening at highway speeds where my safety and the safety of others will be jeopardized. ***I have a video I can send you but the link below does not allow mp4 files***

I am reporting a severe, intermittent loss of Electronic Power Steering (EPS) assist on a 2022 Ram ProMaster cargo van at ~21,000 miles. The defect causes sudden drops in steering assistance and erratic wheel-jerking under heavy electrical loads during rapid, low-speed turns while parking.A professional dealer teardown and inspection at Dutch Miller Ram confirmed that environmental rainwater from the windshield cowl completely breached the factory weatherproofing seals. Standing liquid was found pooling inside the bottom floor of the connector housing, causing severe copper oxidation (galvanic corrosion) and visible electrical arcing on a constantly energized 12V male pin inside the EPS gear cylinder. This high-current bottleneck drops voltage under load, causing the internal ECU to cut assist as a safety fail-safe.Critically, this design defect created an immediate, progressive cascading failure dating back to the very first month of ownership. Because this 12V power line remains constantly "hot" while parked, the pooling water established an un-metered short-circuit bridge directly to the frame ground. This forced an aggressive parasitic electrical drain that repeatedly flattened the battery after sitting for short two-week intervals throughout its lifespan, destroying the original factory battery.The dealer's safety protocol requires a complete steering rack replacement. However, because Ram recognized this vulnerability, they completely superseded the part with a redesigned assembly that forces consumers to purchase new, non-faulty tie rod assemblies just to make it compatible, inflating costs to over $6,000. This data directly supports the active NHTSA investigation into 2022-2023 ProMaster steering modules. Furthermore I imagine that since some people may continue to drive the vehicle under this particular condition of "barely being affected" until there is sudden failure on the highway or zero signs prior to catastrophic failure. I STILL OWE $ ON THIS VEHICLE

The power steering for my 2022 Ram Promaster failed on 3/7/24. The safety issue this caused was that steering the van was nearly impossible. Fortunately, the failure occurred while I was in a parking lot. The van had to be towed to the local dealer. The defective parts were on backorder (part number 6TB16JXWAC Module-steering control) and arrived on 5/21/24. This was covered under warranty and the repair work was done by the local dealer. There weren't any warning lamps that would indicate an issue. I used the van to drive to the jobsite, worked for a few hours, and the issue occurred as I was leaving for the day.

While driving, the power steering stopped and basically locked up the steering wheel almost causing an accident. At the same time, multiple warnings flashed on the dash. After restarting, the vehicle operated as should until the following day when it occurred again and we had to have it towed to the dealership. Water intrusion and corrosion damaged a wiring harness and rack and pinion. The cost to repair was $5200. The dealership we use is Diehl Automotive. 6181 Steubenville Pike, McKees Rocks, PA 15136. They told me this is the 12th van they've had this happen to. They told me to report this incident since it is a safety hazard and the vehicle is only 4 years old.

The contact called for the owner of a 2022 Ram Promaster 3500. The vehicle was taken to be serviced due to a power steering failure. While operating the vehicle, the owner experienced a power steering failure, and the steering wheel was difficult to turn to the left or the right. The messages "Service Power Steering", "Service Hill Assist", "Service Collision Warning", "Blind Spot Alert Unavailable", and “Service ESC" were displayed. The contact diagnosed the vehicle and determined that water was inside the main steering connector, causing the power steering failure. The owner was informed that the steering rack needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were not contacted. The contact was informed of NHTSA Action Number: PE26002 (STEERING, ELECTRICAL SYSTEM). The contact stated that the vehicle had experienced the failure listed in the investigation. The failure mileage was 68,974.

Less than a half mile into my work day the van started flashing all warning lights ( Hill assist, power steering, service engine, abs ETC.) I was on a busy road and was attempting to pull off to safety But the van turned off. Was able to jump it after 2 attempts and get it to the dealer 1 mile away, without any other lights coming back on aside from CEL. Dealer informed me I have 2 Corroded wiring harnesses, bad rack & Pinion and alternator is at 7%.... From what I've heard, this is a problem that could have been prevented by the manufacturers.. I also had a Transmission replacement at 30k miles and full Engine replacement at 55k miles. Currently at 80k Miles... This is Unacceptable for a Commercial fleet vehicle.
